1. Powered by light energy: The solar

cell installed converts light energy into

electrical energy, and stores it in the

rechargeable battery.

2. No need for battery replacement:

The watch is provided with a rechargeable

solar cell instead of the conventional

silver oxide battery.

3. Large volume rechargeable battery:

When the watch is fully charged, it will

keep operating for approximately 50 days.

4. Energy depletion forewarning function:

When the energy stored in the rechargeable

battery is reduced to an extremely small

amount, the second hand starts moving

at 2-second intervals.

5. Quick-start function: Even when

the watch completely stops operating,

it will start operating immediately once

exposed to light.

■ HOW TO CHARGE AND START

THE WATCH

Before using the watch, be sure to charge

the rechargeable battery sufficiently by exposing

the watch to light.

1. Expose the watch to sunlight or strong

artificial light of more than 1,000 lux

(for example, two 15-watt fluorescent

lights with a distance of 70 cm between

the watch and the light source).

It will start operating immediately with

the second hand moving at 2-second intervals.

* While the second hand is moving at 2-

second intervals, the energy stored in

the rechargeable battery is not sufficient.

If the watch is turned away from the

light, the watch will stop operating.

2. Keep the watch exposed to the light

Caution:

While charging the watch, make sure that the

watch temperature does not exceed 50° C.

daily for about 3 hours.
